SPRING-WIRE MATTRESS.

SPECIFICATION formingpart of Letters Patent No. 694,614, dated March 4,1902. Application filed March 20, 1901. Serial No. 52,038. (No model.)

To all whom it may concern.-

Be it known that I, CLARENCE H. GLOSTER= MAN, a citizen of the UnitedStates of America, and a resident of Cincinnati, in the county ofHamilton and State of Ohio,"have invented certain new and usefulImprovements in Spring- Wire Mattresses, of which the following is aspecification.

The object of my invention is a spring-mat- 1o tress in which while thecoils are held securely in place they are not knotted, and each coil iscrossed by only two tie-rods, which cross each other at the-center ofthe coil, the coils being held in place upon the tie-rods by links,

which are of a construction such that they may be fastened in placesimply and quickly.

This object is attained by the means described in the annexedspecification and illustrated in the accompanying drawings, in which-Figure 1 is plan view of a corner of a mattress embodying my invention.Fig.- 2 is a longitudinal sectional View taken through the center of oneof the coils, the lower end of the coil being broken off and the tie-rodbeing shown in elevation. Fig. 3 is a perspective View of two coils upona tie-rod connected by a link. Fig. 4: is a detail View, upon'anenlarged scale, of the link shown in Fig. 1. Fig. 5 is aslightly-modified form of-link. Fig. 6

shows the link in Fig. 5 in use.

Referring to the parts, frame A is of the ordinary construction and isto be used in combination with a similar lower frame, as is customary.The tie-rods and links will be de- 3 5 scribed as connected at the topof the coils, it

being understood that they are to be connected at the bottom in asimilar manner, as is likewise customary. The upper and the lower end 1)and b of coils B are free-that is, are

0 not twisted about a loop of the coilthat is, they are not knottedcoils. Tie-rods 0 pass under the top loop I). of each coil and have foreach coil two double curves, the downturned bends c of which seat saidupper loop, the up- 4 5 turned bends 0 coming within the loop. Thesetie-rods run longitudinally and transversely across the'frame of themattress at right angles to each other and cross the coils upon theirdiameters. Links D connect the coils,

adjacent on the tie-rods, to one another. Each link has a U-shaped loopat each end, which fits into the upturned bend c of the tie-rod andthence passes over the top of loop b of the coil to the next coil,passing over its top loop and into the next bend a of the rod. TheU-loops are themselves bent down at an angle to the rest of the link, soas to pass readily over thetopof loops 12 In the form shown in Fig. 1these U -loops upon a link are turned in opposite directions, andbetween the coils the link is brought underneath the tie-rod. In theform shown in Fig. 6 these loops are upon the same side of the link, andbetween the coils the link runs parallel to the tie-rod. It is seen thatwith this construction the clamping action where the coil, the tie-rod,and thelink meet is of so firm a nature that there is no tendency toslip or slide in their seats or bends c", that therefore the coils neednot be knotted, and that they are held in fixed relation to one anotheron the rods.

The method of putting the parts together is as follows: One of theU-loops of each link has its end left straight, as shown in dottedlines, Figs. 4 and 5. One coil having been placed in the bends o of thetie-rod, the U- loop with the downturned end is slipped into the bend 0adjacent to said bend o. v coil is then placed on the tie-rod in thenextbend c, the straight end of the U-loop of the said link is slippedthrough the next bend c, and said straight end is then bent down with aninstrument, so that in securing a link in place the only point at whichany bending or the use of an instrument is necessary is this onefinishing step of turning down the straight end of one Uloop--a simpleoperation, which may be quickly done.

What I claim is 1. In a spring-mattress in combination tierods having aseries of double curves each consisting of a downturned and an upturnedbend the downturned bends to seat the loops of the coils of themattress, and linksbetween the coils adjacent to the tie-rods and whoseends are bent to pass over said loops of the coils and to seat in theupturned bends of the double curves, substantially as shown anddescribed.

2. In a spring-mattress the combination of a series of coils, tie-rodsrunning diametrically across the coils at right angles to each otherbeneath the top loops of the coils and having a series of double curvesconsisting of The next an upturned and a downward bend the latter toseat said loops, andlinks between the coils adjacent to the tie-rods andhaving U-loops at their ends to pass over the loops of the coils andseat in the upturned bonds of the tie-rods,substantially as shown anddescribed.

3. In a spring-mattress the combination of a series of coils, tie-rodshaving a series of double curves each consisting of an upturned and adownturned bend running diametrically across the coils at right anglesto each other beneath the top loop of the coils so that the loops seatin the downturned bends and the upturned bends come Within the loops,

and links between the coils adjacent to the 15 double curves thestraight end may be pushed 20 through the next of said bends and securedin place at one operation, substantially as shown and described.
